Product Description
General Description
The check valve's main function is to prevent medium flows backward, achieving the release of the medium. Lift check valve's main components are valve body, bonnet, disc, seat, spring. When the fluid flows along the desired direction, the fluid overcomes the spring force to push the disc, thus opening the valve and allowing the fluid to pass. When the fluid comes from the negative direction, the fluid pressure and spring force impact the disc simultaneously, then the valve is sealed.
